Backwards Compatibility Changes#

Users of the Rust extensions and/or rhg should be aware that the new Rust index can result in a performance degradation for push/pull on repositories

  • not* using persistent-nodemap (see hg help config.format.use-persistent-nodemap).

If this is something that matters to you, please reach out to us as this is not an insurmountable obstacle. This is a choice base on the assumption that there are few people in this situation and our time should be spent on more pressing matters.
